When a permit is required

Permit triggers and exempt work for Dallam County

No verified countywide general building-permit requirement was found for ordinary building construction in unincorporated Dallam County. Verified county approvals and controls include subdivision plat approval under county subdivision regulations, OSSF permitting and inspection under TCEQ rules, county notification and inspection for utility work in county rights-of-way, and floodplain administration contact where applicable.

Owner-builder: For unincorporated residential work, HB 2833 private-inspection rules may be relevant depending on project type and legal applicability.
